When creating a Chrome extension, you need to provide a set of icons for context menus, browser actions, page actions, and the Chrome Web Store. Usually, these are just resized versions of the same image. The goal of chrome-manifest-iconify is to intelligently handle the tedious process of generated all these resized clones. All you need to do is provide it a master icon and v2 manifest file. It will parse the manifest to determine the sizes, names, types, and paths of the icons it needs to generate. You can choose from several resizing algorithms as provided by Sharp so your entire icon set looks awesome.

npm install --save-dev chrome-manifest-iconify

Options:
  --help             Show help                                         [boolean]
  --version          Show version number                               [boolean]
  -i, --master-icon  Path to the master icon                 [string] [required]
  -m, --manifest     Path to the v2 manifest.json
                                             [string] [default: "manifest.json"]
  -r, --resize-mode  Algorithm for resizing the master icon
     [choices: "nearest", "cubic", "mitchell", "lanczos2", "lanczos3"] [default:
                                                                     "lanczos3"]
  -o, --out-dir      Directory to write the icons                       [string]

Examples:
  chrome-manifest-iconify -i master.svg
  chrome-manifest-iconify -i master.jpg -m src/manifest.json -r nearest -o
  build/icons

Instead of directly using this API, you might find it easier to use the Gulp plugin gulp-chrome-manifest-iconify for your project.

The chrome-manifest-iconify module

Example

const chromeManifestIconify = require('chrome-manifest-iconify');

const loadIcons = async () => {
  try {
    const icons = await chromeManifestIconify.async({
      manifest: 'src/manifest.json',
      masterIcon: 'img/test-icon.png'
    });

    // Do stuff with icons
    const buffers = await Promise.all(icons.map((i) => i.contents));

    console.log(buffers);
  } catch (err) {
    // Oh, no! Something bad happened
    console.error(err);
  }
};

Generates icon set for a Chrome extension by parsing the v2 manifest. Note that this function does not actually write the files.

Kind: static method of chrome-manifest-iconify
Returns: Promise.<Array.<module:chrome-manifest-iconify.Icon>> - A promise that resolves with the generated Icons
